Caerleon Safford of Fire Safe Sonoma delivers a great presentation on protecting your home from wildfire with a focus on home hardening or the "structural" things you can do to help withstand embers penetrating your home or structure.
The host of this video is fire researcher Jack Cohen. He takes you through an example home and demonstrates how well a home can survive when proper home hardening techniques and defensible space measures are taken.
Watch this video and look at all of the obstacles to evacuation and how the heavy smoke obscures visibility.
Roadside clearing and defensible space are two very important aspects of having the chance to escape a fast moving wildfire.
